reMarkable marker cap

thingiverse

This cap provides a safe and reliable cover for the reMarkable marker or pen, whose delicate felt tips are extremely sensitive. Printed in single-outline mode without bottom and top layers from any flexible material, this cap will fit the pen perfectly. Since it requires only 10 centimeters of filament, there's no need to purchase an entire roll to protect your valuable investment. The tip is carefully shaved off to prevent mold growth on the felt tip, but you have the option to do so yourself.
